I'm writing Excel formulas into a codebook for statistics class. There are lots of formulas. I think I have them all correct and then I look and a number has spontaneously mutated. I look and another one has. All perfect, all set, and then another formula has transformed itself. It's like whack-a-mole trying to get all those formulas perfect and set.
With words there is room for creativity and imperfection. With science there must be a perfect structure, or as nearly perfect as can be. The better the structure, the better our conclusions and predictions.
